Fix bug when applying R_SPARC_GOTDATA_OP* relocations to local symbols.
When applying a GOTDATA_OP* relocation to a local symbol, the addend is being applied after getting the value of the symbol. When the relocation refers to a merge section, however, the addend must be provided when computing the symbol value, since the contents of the section may have been rearranged. gold/ PR gold/18855 * sparc.cc (Sparc_relocate_functions::gdop_hix22): Remove addend parameter. (Sparc_relocate_functions::gdop_lox10): Likewise. (Target_sparc::Relocate::relocate): Use addend when computing symbol value for R_SPARC_GOTDATA_OP*.
